Self-centering laminated process for corrugated containers and blank therefor

Abstract

A process for the automatic centering of a corrugated liner onto a corrugated blank, comprising the steps of providing a pair of opposed, longitudinally extending first fold lines in the blank with the distance between the first fold lines being the width of the liner and defining therebetween a central portion on the blank; providing a pair of longitudinally extending second fold lines adjacent the sides of the blank and that are parallel to the first fold lines, the first and second fold lines being spaced apart a distance equal to the thickness of the liner and an outer edge panel being defined on the blank between the second fold line and the sides of the blank; gluing the liner generally onto the central portion of the blank; folding the outer edge panels 90.degree. upwardly about the first fold line; and bending downwardly the outer edge panels another 90.degree. to contact the liner. A blank for use in such process is also disclosed.
